Barkley continues work with personal coach of Brady, Ryan

Barkley continues work with personal coach of Brady, Ryan

Atlanta Falcons quarterback Matt Ryan spent last offseason working with Tom House and Adam Dedeaux on his throwing mechanics.

Ryan went on to set career-bests in completion percentage (69.9), yards passing (4,944), touchdowns (38), interceptions (7) and passer rating (117.1).

New 49ers quarterback Matt Barkley worked with House and Dedeaux for the fourth offseason in Southern California before reporting to Santa Clara for the team’s offseason program.

“Kyle (Shanhan) is on board with what House and those guys are doing – I think, really, because of the year Matt Ryan had,” Barkley said on “The 49ers Insider Podcast” on NBC Sports Bay Area.

“He’s a believer in that. He saw the benefits of what Matt did with some of his drops and the timing on routes, how he changed his feet on some things. So we’re kind of sticking with that plan. Everyone is a little different, but for the most part we’re all on the same page when it comes to what our drops are looking like, our footwork and how the ball is coming out.”

House is a former major league pitcher and pitching coach who founded the 3DQB training facility in Los Angeles. Dedeaux pitched at USC and is the grandson of USC baseball coaching legend Rod Dedeaux. Former NFL quarterback John Beck is a motion mechanics instructor.

Tom Brady, Drew Brees, Alex Smith and Carson Palmer are among the NFL quarterbacks who have worked with 3DQB.

“I believe in those guys and what they’re doing,” Barkley said. “They’re at the top of their game, working with Brady and a bunch of other guys. They’ve helped me.

“He won’t change your throwing motion or really tweak how the ball comes out, but he’s going to try to maximize velocity and ground force production and torque -- a lot of sports science terms. But, really, just maximizing efficiency with your motion and making sure you’re sequencing is right.”

Barkley had never played for Shanahan before signing a two-year contract with the 49ers on the first day of free agency. But there are two obvious connections. Barkley’s offensive coordinator last season with the Chicago Bears was Dowell Loggains, Shanahan’s quarterbacks coach in 2014 when Shanahan was the Cleveland Browns’ offensive coordinator. The other connection is House.

"It’s kind of funny, he worked with Atlanta’s staff all of last year, helped Matt Ryan, kind of build his base from the ground up and helped him a lot and he had an MVP year," Barkley said of House.

"There may have been talks down the pipeline, who knows. I don’t think that was the deciding factor by any means, but it never hurts.”

John Lynch hires new 49ers director of pro personnel

John Lynch hires new 49ers director of pro personnel

General manager John Lynch made his third high-profile addition to his personnel department on Friday with the announcement of Ran Carthon as director of pro personnel.

Carthon assumes the position that Mike Williams held with the 49ers through the draft. Williams worked 14 seasons in the 49ers’ scouting department, including the final four as director of pro personnel. Assistant director of pro personnel Quentus Cumby was also fired after the draft.

"We want to welcome Ran Carthon and his family to the 49ers," Lynch said in a statement. “Ran has a clear vision for how he plans to run our pro personnel department, and was excited about the opportunity to blend his approach with ours. Having previously directed his own pro department, we expect Ran to hit the ground running and help us build the strongest roster possible.”

Carthon spent the previous five seasons with the Rams organization in the same position he now holds with the 49ers. The Rams fired Carthon three weeks before the draft.

According to the 49ers, Carthon’s role will consist of managing “the coordination and day-to-day operations of the pro personnel department, including assistance with the coordination of free agency, the evaluation of the unrestricted free agent market and oversight of the evaluations of NFL players.”

He will be asked to provide input into all personnel decisions when the addition of veteran free agents is considered. He will also provide input into personnel decisions concerning the team’s acquisition of veteran talent through free agency, trades and the waiver system. Carthon will also oversee the scouting reports for upcoming opponents to help prepare the coaching staff prepare its game plan.

Lynch hired two key members of the personnel department immediately following his appointment to the position. He hired former Denver Broncos executive Adam Peters as vice president of player personnel and former Detroit Lions general manager Martin Mayhew as senior personnel executive.

Carthon, 36, had a brief NFL career with the Indianapolis Colts as a running back. He also spent time with Green Bay,  Seattle and Detroit.

His father, Maurice Carthon, played eight seasons in the NFL as a running back with the New York Giants and Indianapolis.
